PHARMACEUTICAL  GLEANINGS. 
Oil  of  Morphia,  Insolubility  of  Morphia  in  Chloroform, — A 
few  months  ago,  (Jan.  1854,)  we  published  a  short  note  in  refer- 
ence to  "oil  of  morphia,"  as  described  by  M.  St.  Lager,  in  which 
chloroform  was  the  medium  of  solution.  M.  Lepage,  (Jour,  de 
Pharm.,  Avril,  1854,)  refers  to  a  previous  article  by  himself,  on 
the  solvent  powers  of  chloroform,  in  which  it  is  stated  that  mor- 
phia and  its  salts  are  insoluble  in  that  liquid,  and  then  by  new 
essays  confirms  his  previous  results,  proving  that  M.  St.  Lager's 
process  cannot  be  followed. 
The  sulphate  and  hydrochlorate  of  morphia  being  but  slightly 
soluble  in  fixed  oils  at  the  ordinary  temperature,  but  more  so 
when  hot,  M.  Lepage  recommends  that  the  mixture  of  almond 
oil  and  hydrochlorate  of  morphia,  should  be  heated  just  before  it 
is  to  be  used. 
As  a  substitute  for  the  "oil  of  morphia,"  M.  Soubeiran  sug- 
gests a  solution  of  morphia  in  glycerin,  viz  : 
Acetate  of  Morphia,  six  grains, 
Glycerin,  a  fluidounce. 
Dissolve  the  morphia  in  the  glycerin  with  or  without  heat.

this  preparation,  are  taken  from  the  London  Pharm.  Journal,
